BATTERY CELL.
Application filed May 16, 1924. Serial No. 713,642.
a battery cell of this type which will have a long life with increased efiiciency bv-forming the cell structure so as to provide for the variablecorrosive attacks on the outer metallic container so far as possible.
Heretotore battery cells of this type have been built whereby the greatest internal resistance is in proximity to the bottom of the cell, and is relatively less near the top resulting in the greater current flow. near the top of the cell. Such conditions cause the outer metallic container to be attacked andeaterbaway near the top margin. or upper portion, while the-lower portion has not been consumed to any great extent.
My improvement, in its broadest aspect, embodies a dry-battery cell having a thickened metallic wall surrounding the upper part of the cell whereby the consumption of the metal may be proportioned to the normal current-flow from the cell. My invention comprises not only the cell structure in which the mass of the metallic containeris increased adjacent the zone of greatest corrosion as just explained, but also the specific details of construction hereinafter set forth in the drawings and this specification and then particularly pointed out in the appended claims.
Referring to the drawings, Fig. 1 is a. central longitudinal sectional view of one form of battery cell embodying my improvements; and I I Fig. 2 is a transverse sectional view of the cell taken on the line 2-2 of Fig. l-looking in the direction of the arrows.
Similar numerals refer to similar parts throughout the several figures.
In the drawings the outer cylindrical metallic vessel 3, preferably of zinc and forming the anode of the cell, contains the inner it known that I. ROBERT S'rL'Aur cathode 4, preferably of carbon, having the neck 5 passing through the cover 6, the top of the neck having the binding-postimounted thereon. The cathode 4 is centrall disposed within the Zinc vessel 3 as shown in the figures, and the vessel 3 also carries inner surface of the vessel 3 as shown. The vessel also contains the battery-filling material 9, such as an admixture of ammonium chloride and manganese dioxide,.\vhich is packed about the cathode 4 beneath the cover 6 as is'customary in dry batteries.
In F ig. 1, I have shown one practical form of thickening or increasing the mass of zinc or other suitable metal around the upper portion of the vessel 3 by bending over the upper margin 10 of the metallic zinc until such margin is in surface-to-surface contact: with the outer periphery of the vessel 3. The binding-post 11 is secured to the annular fold at the top of the zinc vessel 3 as shown. By this construction the to the bibulous lining 8 secured against theupper portion of the zinc vessel 3 has a double thickness of zinc metal which effectively provides for the unequal corrosion of the zinc t the top of the outer vesselbecause of the inequalitiesof the current flow and thereby lengthens the life of the battery cell when in use.
My invention, in its broadest aspects, is not limited to this particular construction shown or to any particular construction or arrangement of parts, or to any particular.
battery elements, as changes and alterations p maybe made in the battery cell construction illustrated or in the elements] employed without departing from the principles of the invention and without sacrificingits chief advantages. r
